چکیده
In this study, a robust model predictive controller is designed for the trajectory tracking problem of non-holonomic constrained wheeled mobile robot based on an elliptic invariant set approach. The time-varying error kinematics and uses linear matrix inequalities to solve taking uncertainties into account. are modelled by fractional transform form contain both parameter perturbations external disturbances. control strategy consists feedforward term that drives centre ellipse reference point feedback converges uncertain system state equilibrium point. stabilises nominal ensures all states remain within ellipsoid at each step, thus achieving stability system. Finally, robustness algorithm its resistance disturbances verified simulation experiment.

Finite Horizon Robust Model Predictive Control Using Linear Matrix Inequalities
In this paper, we develop a finite horizon model predictive control algorithm which is robust to model uncertainties. A moving average system matrix is constructed to capture model uncertainties and facilitate future output predictions. The paper is focused on step tracking control. Using linear matrix inequality techniques, the design is converted into a semi-definite optimization problem. Clo...

The primary disadvantage of current design techriiques for xriodel predictive control (MPC) is their inability to deal explicitly with plant model uncertainty. In this paper, we present a new approacli for robust MPC synthesis which allows explicit irlcorporation of the description of pla,nt uricertainty in the problem formulation. The uncertainty is expressed both in the time domain and the fr...

Abstract—This paper presents a tracking control strategy based on Lyapunov approach for nonholonomic wheeled mobile robot. This control strategy consists of two levels. First, a kinematic controller is developed to adjust the right and left wheel velocities. Using this velocity control law, the stability of the tracking error is guaranteed using Lyapunov approach. This kinematic controller cann...
